Statistical analysis of the influence of body height of ATP players on the success of their game
Nechanický, Michal ; Kočíb, Tomáš (advisor) ; Carboch, Jan (referee)
Title: Statistical analysis of the influence of body height of ATP players on the success of their game Objectives: The aim of my bachelor's thesis is to determine whether a player's body height affects his position in the ATP rankings and whether it affects the effectiveness of his serve. At the same time, I will investigate the possible influence of surfaces on player's serve statistics and his position in the ATP rankings. Methods: The mentioned monitoring was determined on a sample of TOP 200 players of the ATP ranking. Mathematical-statistical analysis of the data was carried out by collecting the data reported on the official ATP website. The results of my investigation were compared with similar characteristics of selected professional literature. Results: Mathematical-statistical analysis showed a loose correlation between a player's body height and his position in the ATP rankings. Furthermore, a stronger correlation was shown between serve statistics and ranking and between serve statistics and player height. This correlation changes with the type of surface, where the most closeness to the player's position in the ATP ranking or his body height is shown by the serve statistics of the player serving on a hard surface. Keywords: Tennis, body height, serve, surfaces, ATP

Growth of the foot in children aged 6 - 15 years. (Probe to the 6th nationwide anthropological survey of children and adolescents in the Czech Republic 2001.)
PAVLEČKOVÁ, Jana
The thesis is focussed on the issue of the growth and development of children aged 6-15 years in the Czech Republic. Data on children?s growth and development is determined within the framework of nationwide anthropological surveys of children and adolescents. In this case, it is a supplementary probe to the 6th National Anthropological Survey of 2001, which determines 4 bodily dimensions among children: body height, body weight, foot length and foot width. All of the obtained information and data was entered into a questionnaire specially prepared for the 6th NAS. The measured data was then saved, sorted, controlled and statistically processed. Furthermore, the basic bodily dimensions were used to calculated the following indexes: BMI, index of foot length to body height, index of foot width to body height and foot length-to-width index. The results of statistical processing of the measured data were then entered into table and graphs, and compared with literary information.

Differences in growth parameters in SGA / IUGR children and patiens with growth hormone deficiency treated with recombinant growth hormone
Kročilová, Kateřina ; Sedlak, Petr (advisor) ; Lisá, Lidka (referee)
In the Czech Republic is born to 5 % of SGA / IUGR children, about 5, 000 children a year, and their incidence is increasing. In 10 - 15 % does not occur postnatal compensation growth acceleration and growth retardation is then further deepens. Since 2003, these children can be treated by recombinant growth hormone in supraphysiological doses. Master thesis brings informations about SGA / IUGR children and their growth parameters during the first 2 years from the beginning of treatment when the monitoring was carried out at three - month intervals. The results are compared with the group of patients treated with growth hormone for growth hormone deficiency. Growth data was processed by a group of 57 SGA / IUGR children, which was compared with data of 34 children with growth hormone deficiency treated between 2003-2015 with growth hormone. Treatment of both groups of patients was carried out by a suitable therapeutic protocol, with the dose of GH by the respective diagnosis. These parameters were monitored: body height and weight, growth rate, BMI and weight - height ratio of patients. SGA / IUGR and GHD patients showed different growth profile in the initial phase of treatment when GHD patients had higher acceleration peak after 3 months of starting treatment and steeper increase in growth rate....

Selected parameters of gait and foot in consideration of the individual's body height
Strnadová, Hana ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: Selected parameters of gait and foot in consideration of the individual's body height Objectives: This thesis deals with a dependence of the selected gait and foot characteristics on a person's body height. These parameters are compared between a group of men and a group of women. In addition, a validity of selected formulas used for a determination of body height is evaluated. Methods: Mutual relation among the gait and foot characteristics and the individual's body height is observed. The thesis is a descriptive - association research, the comparative method is chosen in the practical part of the thesis. For an objectification of the research, the Plantograph and the 3D kinematic gait analysis performed by Qualysis system was used. Results: It was found out that the selected formulas used for a determination of body height are valid. The best results are brought by the formulas which count with a length of a bare foot, the length of a step and a double-step. On the contrary, the worse results are achieved by using the formulas which count with the dimension of shoe print. A tight dependence of the foot length and the length of the step / double-step on the body height was proven. A minimum dependence of the foot width on the body height was proven. Nevertheless the foot width is verifiably...

Relations between high, jumping and speed-dexterity parameters in older students' volleyball
Valtová, Alžběta ; Vorálek, Rostislav (advisor) ; Buchtel, Jaroslav (referee)
Title: Relations between high, jumping and speed-dexterity parameters in older students' volleyball Objectives: The aim of this work is to identify and evaluate the relationships between high, jumping and speed-dexterity parameters in older students' volleyball in the years 2008 to 2012. Methods: For the processing and evaluation of data retrieved from the results of standardized tests for volleyball in individual years and generally used method of comparison (comparison) data were also used basic statistical methods (arithmetic mean, standard deviation, maximum, minimum, range of variation, T-sections, McCall criterion). The evaluation was performed by means of graphs and verbal assessment. Results: In the selection of the 20 highest players in each year from 2008 to 2012 could not be confirmed that the majority did not reach above the average of the absolute values after smash jump start, but it was confirmed that the majority did not reach above-average values when measuring speed-dexterity test, known as K-test measured against a whole group of players in a given year. Furthermore, according to the processed data confirmed that most of the selection of 20 of the K-test the best players in each year from 2008 to 2012 will achieve above-average values of the absolute jump start after smash...

The relation between morphological and personality traits in humans
Sýkorová, Kateřina ; Flegr, Jaroslav (advisor) ; Třebický, Vít (referee)
In humans, as in animals, associations or correlations between morphological and personality traits can be observed. Some of the most conspicuous and well describable morphological traits in humans are eye color, hair color, body height and body mass index (BMI). These traits can correlate not only with temperament or character, but also, for example, with intelligence. Relations between morphology and personality can have an origin on a genetic or an environmental level. The human psyche, which can be influenced by social factors, can also have a role in the chain of causes and consequences. In this study, known relations between morphological traits and personality are discussed and mechanisms which could be responsible for these relations are mentioned. This study also focuses on the possible role of the environment which could explain some associations between the traits. Further, there is an attempt to identify environmental factors contributing to the morphological and personality traits which could therefore be a cause of some correlation between these traits.

Effects of body height on movement competences of pupils
Sláčíková, Barbora ; Vojtíková, Lenka (advisor) ; Kainová, Lucie (referee)
This thesis focuses on the evaluation of how body height, BMI, gender, and leisure-time physical activities affect movement competence of pupils. The theoretical part analyses the younger school age and its characteristics in physical, psychical, movement, and motoric development. We further also analyze how movement activities affect child's organisms. The critical chapter of the theoretical part is a chapter about growth and development. Additionally, we add information about anthropometric and somatic changes in the younger school age. At the end of the theoretical part, we provide an overview of methods that can be used to measure movement competence. We mainly elaborate on MOBAK 3 method, which we chose to use in our research. The research part describes the selected research and statistic methods, research sample, and results. The data showed that there is no significant relationship between body height and movement competence. However, we found significant relationships with the other variables - BMI, gender, and leisure-time physical aktivity. KEYWORDS younger school age, body height, movement competence, motoric testing, Mobak

Hominin evolutionary development to the Plio-Pleistocene boundary in relation to body height
Garciová, Rosana ; Sládek, Vladimír (advisor) ; Hoffmannová, Eva (referee)
Body height is the main characteristic of human. It can be variable to the relation to the environment. Development of the height is primarily determined genetically, but an environment has a partly influence. An evolutionary view is very important, especially in the identification of fossils at the Plio-Pleistocene boundary and the overal view on individual development to 2.5 million years ago and characteristics of our ancestor. This bachelor thesis summarized the methods how to estimate the most accurate body height of fossil Homo and compares individuals between them. It also focuses on the geographic area of genus Homo not only on the period and if there is a correlation with increase or decrease in the height of an individual. The main finding of this work is diversity within species Homo. Homo habilis had reached the height of range 120-155 cm. In contrast, Homo ergaster measured up to about 170 cm. While Australopithecines were lower growth. Australopithecus were tall on average around 114 cm and Paranthropus exceeded them at range 10 cm. Slight differences in body height can be seen in the context of sexual dimorphism. The climate in Plio-Pleistocene had no influence on the change in height. Rather, the geographic area of occurrence of our ancestor played a role here. Key words:...
